I was divorced in 2000. The judge gave my ex our youngest son to claim on his taxes . I got the 2 older children. My ex has not worked in 2 years , and is in 17,000.00 arrears in Child Support. My youngest son who he gets to claim, has never lived with him , and has no contact with him . I have been remarried now for 5 years , and my husband now is the one who has supported my son all this time. My ex cannot claim him on his taxes since he has not worked in 2 years , and I was wondering can my now husband claim my youngest son on our taxes ?
